DOOR FOR BAKERS OVENS.

Specification of Letters Patent.

Application filed May 26, 1910. Serial No. 563,555.

To all whom it may concern:

Be it known that we, FRANK H. VAN HOUTEN and DAVID J. HANNA, citizens of the United States, residing at FishkillontheHudson, county of Dutchess, and State of New York, have invented certain new and useful Improvements in Doors for Bakers Ovens; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

The object of the present invention is to provide an oven door for use in bakers ovens which will permit of a wide opening being formed in the oven so as to facilitate the rapid handling of the dough or loaves and, at the same time, permit, if desired, a portion of the opening to remain closed during inspection or when the dough or loaves are to be handled in one part only of the oven.

The invention consists broadly in an oven door construction embodying a door frame having a horizontally elongated opening adapted to be closed by a plurality of inclependent doors arranged side by side, each counter-balanced independently of the other, and a supplemental pivoted door or tongue for closing the space or joint between adjacent doors but capable of being moved by either of the main doors when the latter are moved to their open position.

The invention further consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described and pointed out particulady in the appended claims.

In the accompanying drawings-Figure 1 is a front elevation of an oven door construction embodying the present improvement. Figs. 2 and 3 are transverse sectional views of the same, Fig. 2 showing the doors in their closed position, and Fig. 3 showing one of the doors open. Fig. at is a detail elevation partly broken away showing the meet-- ing edges of the 'two main doors, the tongue or supplemental door and the bracket 01; hanger for supporting the proximate ends of the door shaft. Fig. 5 is a similar View with one of the doors swung into its open position.

The doors when closed normally occupy a l slightly inclined position within the jamb of the door frame, as indicated in Fig. 2, their outer edges resting on or in proximity to adjustable angle flanges construction.

F of the usual I The proximate edges of the j doors, it is obvious, must be slightly separated one from the other so as to avoid inj terference even if subjected to high temperatures and, in order to close the opening j thus left without in anywise interfering with the operation of the doors, or leaving an obstruction in the opening when both doors are open, a supplemental door or tongue H is pivotally mounted in position to hang down against the inner faces of the proximate ends of the doors so as to bridge and close the aforesaid opening. Conveniently, the said supplemental door or tongue H is bifurcated at its pivotal end so as to embrace the hanger or bracket F whereby it it is kept in proper position longitudinallyof the axis audit is mounted on the ends ofthe shafts with sufficient looseness to insure its entire freedom of movement,v whereby it will invariably follow the doors as they are being moved to their closed position. Obviously, the supplemental door or tongue will be picked up or swung to open position by the first one of the main doors to be opened and it will be held by the door last to be closed; but in no event can it interfere with the opening or closing of the doors and when both doors are closed the opening between them will also be closed.

The ends of the door shafts are supported in bearings in the jamb frame as is usual in this class of devices and the space between the said shafts and the top of the jamb frame is closed by a'front cover plate K which, at the'center may have an opening elosed'by a supplemental cover plate 70 with a window a therein throughwhich the interior of the oven may be viewed.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent of the United States is 1; In a door for bakers ovens, the com- 1 bination with the door frame having an elongated openin of a plurality of doors independently pivoted on an axial line in proximity to the top of the opening, and a supplemental door loosely supported in po .sition to restagainst the proximate ends;

2. In a door for bakers ovens, the combination with the door frame having an elongated opening surrounded by an inwardly extending flange, of a plurality of doors mounted in said opening, independent alined shafts on which said doors are mounted, a hanger for supporting the proximate ends of the said shafts and a supplemental door pivotally mounted on an axis coincident with the axis of the main doors in position to rest upon the proximate ends of the main doors and close the opening therebetween.

3. In a doorfor bakers ovens, the combination with the door frame hamng. an elongated opening therein, an inwardly extending flange surrounding said opening and pockets at opposite ends of the opening, of independent shafts journaled in the flange of the door opening and projecting into the pockets, independent doors mounted on said shafts within the 'door opening, counterweights for the respective doors mounted on their shafts within the pockets and a movable supplemental door for closing the space between the proximate ends of the main doors.
